Which time???

That's the time taken for the body to travel round the circle from its initial position. It could be less or grater than the time period, the time taken for the body to travel a complete circle(2pi).

No problem, figured I might as well post them if I'm doing them for myself anyway!

Original post by ubisoft

Oops, I meant answers as well as questions

I don't really have the time sorry, it's just meant as a quick reference list for me!

When do you use right hand rule and when the left hand?

Should be in my guide under an exam tip ->
Right hand rule for generating an EMF

Left hand rule for the motor effect :smile:

The "right hand grip" rule might also be used for the direction of a field around a current carrying wire.

Yeah, copying and pasting from a pdf gives you messed up formats so you end up having to mess around so much that typing them out isn't any slower.

That's very kind of you did this, I couldn't do that!

I'm planning to ignore the 6-mark question and just try to ace the rest of the paper. If I have time I'll make some bullet points for the 6-marker which should hopefully 2-3 points. Anyone else doing this?

Yeah haha. They're not worth the time. In the same time you could get more marks doing other questions.

Do you think it's worth doing some bullets for the six marker first , then going back to write it out in full if you have time?

Isn't that a bit risky given its only 25 marks? :L

Yeah that's what I meant. I'll write some obvious points down, then come back to it at the end if I have time. Writing in paragraphs takes too much time, while I could be doing calculations much faster.

What?! that's only 25 marks, even if you did get 25/25 (very unlikely, I am only getting 15ish) that would still be a D max

Makes sense! I don't know how many marks out of 6 the QoWC counts for.

I think it's 3 for the answer and 3 for the English. Good compromise getting half marks but with quarter the time
